Transcription and gene regulation - prokaryote v eukaryote - ANSWER Prokaryote - no nucleosome - regulatory sequences immediately available for transcription without having to regulate accessibility and chromatin structure - no nucleus - transcription tightly coupled with translation RNA synthesis - direction - type of bond (between what two things) - incoming nucleotide determined by... - ANSWER 5' -> 3' synthesis - formation of phosphodiester bond btwn/ incoming ribonucleotide ...

In the experiment described that supports DNA as the genetic material: Why does the mouse die if the researcher mixes the complete dead pathogenic strain with live non-pathogenic strain bacteria and then inject it into the mouse? (The first mouse in the figure). - ANSWER The mouse dies because the R strain has been transformed and is now an S strain, capable of producing the virulence factors that make the S strain deadly to mice. This is because as the pathogenic strain is kille...

What are the subunits of 70s and 80s ribosomes and their main functions? - ANSWER 70S has two subunits : 30S is the small submit that decodes mRNA and 50S is the subunit links amino acids together through peptide bonds 80S has two subunits: 40S and 50S: 40S small subunit, analogous to the 30S subunit in the prokaryotic ribosome 60S large subunit, analogous to the 50S subunit in the prokaryotic ribosome The ribosome consists of both ribosomal RNA and ribosomal proteins. Whic...

Foreign DNA is inserted into the genome - ANSWER What is the meaning of the term transgenic? The transgenic mouse is screened to confirm the transgenic gene is present, then it is crossed with another transgenic mouse to start a line of transgenic mice - ANSWER Once an oocyte has been injected with a transgene and implanted into a mouse, what are the steps to obtaining offspring? True (this integration is random) - ANSWER T/F: the transgene is randomly integrated into a mouse gen...

Because the DNA was not destroyed, meaning that the pathogenic strain is still able to be taken up by the healthy DNA, causing death - ANSWER Why does the mouse die if the researcher mixes the dead pathogenic strain with the live non-pathogenic strain bacteria and then inject it into the mouse? When the DNA was completely destroyed; the S strain was no longer able to be pathogenic without its DNA - ANSWER What was the only scenario in which the mouse lives? Why? 3.4 A - ANSWER Ho...

DNA can be both replicated and transcribed into mRNA, which can be translated into protein - ANSWER What is the central dogma of molecular biology? True (this is due to intrastrand crosslinking, in which adjacent nucleotides basepair, causing bubbling) - ANSWER T/F: the addition of bulky aromatic rings and/or exposure to UV light can cause the DNA to "bubble." True - ANSWER T/F: chemotherapy can cause both single and double-stranded breaks in DNA. Damaged DNA can lead to ...

30S + 50S - ANSWER What are the 2 subunits of 70S ribosomes? 40S + 60S - ANSWER What are the 2 subunits of 80S ribosomes? The small subunits (30S/40S) decode the mRNA; the large subunits (50S/60S) catalyze the peptide bond formation of the amino acids - ANSWER What are the main functions of the 2 subunits of 70S and 80S ribosomes? rRNA (it base pairs with itself forming the shape of the ribosome) - ANSWER Which part of the ribosome (rRNA or proteins) determines its shape? rRNA ...

Six principal elements - ANSWER carbon, hydrogen, oxygen, nitrogen, phosphorous, and sulfur. These make up 92% of the dry weight of cells Organic molecules can form three complex shapes - ANSWER straight structures, branched chains, or rings Hydrocarbons - ANSWER carbon- and hydrogen-containing compounds that are hydrophobic Metabolism - ANSWER The sum of all biochemical reactions. Functions of metabolism are: 1. Acquisition and utilization of energy. 2. Synthesis of biomolec...
